I just downloaded the latest app version to my Iphone 12, and there was a new firmware version to be installed to the drone. After installing the new firmware, it came up a “Tips” that said: Please calibrate the accelerometer first! So we started to do the calibration as we always do, but after doing the level, left and right orientations, the procedure stopped, and we can not finish the calibration, and it is not possible to start the motors anymore. Everything else as camera and lights are working normally. What can we do to solve this issue? I would guess that reinstalling the firmware would help, but how do I do that? This is a standard M2, always worked fine until this new firmware was installed.
